Application filed July 2, 191a,. serlai No. 776,903.

To all whom it may concern:

Be it knownthat I, CHARLES E. SMITH, a subject of the King of England,residing in New York city, in the county of New York and State of NewYork, have invented certain new and useful improvements in Tvpe-VVritingMachines, of which the following is a specification.

, My invention relates to mechanism for -.throw of the carriage, eachdevice being preferably adjustable to vary the distance .the carriagewill jump when the correspond ing'key is operated. By the use ofseparate jump-controlling devices, the adaptability .of the machine forvarious uses is increased.

For example, one of the keys may be used for spacing between sentences,the device controlled thereby being set for three, four, or any desirednumber of let ter spaces. A second key may be used for paragraphindentations, the device controlled by Said key being adapted to effecta suitable spacing for this purpose, as, for example, the distance ofeight or ten letter spaces. Either one or both of these superspacingdevices may, in addition, he used forefl'ecting a rapid run of thecarriage in various other kinds of work. Thus, by repeatedly depressingthe key which is set for para raph indentation, the carriage may bequick y advanced great distance. This movementwill be m ch more rapid,and ac complished with less effort than by the use of'the ordinarysingle-space key. One or more of the multiple-space keys may also insome cases be used in tabulator work. Thus one key may be used alone formoving the carriage from one column position tonnother, or additionalkeys may, be selectil'ely Specification of Letters Patent.

sitions in a column, the particular key operated at any time dependingon the position of the first digit or character in the particular lineand column to be written.

W hen eitherof the special keys is operated, the spring-driven carriageis released from the escapement mechanism and put under the control ofa. s ecial super-spacing device, which permits t e carriage to space orjump a fixed distance; and when said key is released the carriage iswithdrawn from the control of the super-spacing device and restored tothe control of the ordinary ls ter-feeding mechanism. Each special keycontrols a separate super spacing member, and the latter is preferablyad ustable to vary the distance-the carriage j umps.-

Normally idle racks are mounted on the machine frame, to beindependently caused by the separate special-spacing keys to shift intolocking connection with superspacing devices or stop-plates on thecarriage, each stop-plate permitting the carriage to jump or advance afixed distance. Each special space also operates to release the carringsand permit it to jump. The stopplates are mounted on a guide on thecarriage, and each stop-plate carries a stoppin which extends into aslot in said guide, the pin being adjustable on the stop-plate to varythe distance the stop-plate can move relatively to the carriage. One ofthe rack bars nay also be formed with rack teeth the column stops of theordinary tahniating mechanism, said. stops being adj ustablelongitudinally of the rack, and also settable into and out of positionto cooperate with the ordinary tabulating counter-stop on the carriage.

The same key -may, if desired, be used alternatively as a tabulator keyor as a multiple-space key for sentence spacing, etc,

and in ieh a case, in order to silence the super 5; devices, the toothor detent on said a? *c with which the rack engages,

; of operative position.

.aple-space keys may be used sepfor different purpQ-ses, as, for exc,sentence spacing, paragraph indenation, spacing between 'columns intabuator work, etc, each stop being adjustable .1: cause the carriage tojump any desired distance, depending on the purpose for which it isused.

Other features and advantages will hereinafter appear.

Fig. 2 is a viewsimilar to th right-hand portion of Fi l, but showing one of theslidable stop-p ates in operated position. Fig. 3 is a fragmentarysectional elevation showing means for swinging the rack bars, and otherdetails of the invention, the lower rack bar being in operated position,and a column stop set to operative position. Fig. 4 shows a guide plateon which the slidable stopplates or jump-controlling devices aremounted. Fig. 5 is a perspective view of one of the stop-plates. Fig. 6isa sectional elevation view-'ofthe machine. Fig. 7 is a perspectiveview showing means for releasing the escapement rack and operating theswinging rack bars. Fig. 8 is a view similar to Flg. 6, but with one ofthe swinging racks in operated position.

Type-keys 1 are mounted on key levers 2 fulcrumed at 3 and operablethrough bell cranks 4 to move the type-bars 5 upwardly to printingposition in front of the platen 6. The platen is shiftably mounted on acarriage 7 driven in letter-feed direction by a spring motor 8 connectedthrough a belt 9 to the carriage, the carriage being guided on a rearguide rail 10 and a front guide rail, not shown. The letter-feed travelof the carriage is controlled by escapement mechanismcomprising-escapement dogs 11 cooperating with an escapement 'wheel 12driven by an escapement pinion 13 which runs in mesh with a rack 14 onthe carriage. Each typebar has a shoulder 15 which, when the typebar isactuated, moves a universal bar 16 z-iarwardly and operates the dogs 11,the re ciprocation of said dogs effecting a letter feed movement of thecarriage in the usual way. The escapement rack 14 is connected to thecarriage by a swinging frame 17 which permits the rack to be lifted fromthe escapement pinion 13 so that the carriage may move independently ofthe es capement mechanism.

In order thatithe" ctiirriage may be moved forwardly a multiple?letter-space distance by the single operation of a space key, thefollowing mechanism is provided. A rockshaft 18 mounted on the machineframe, preferably in rear of the platen and parallel therewith, hassecured thereto upwardly and rearwardly extending arms 19 to which isfixed a rack bar 20 adapted to be swung forwardly to engage a tooth 21on a stop-plate 22 slidably mounted on the carriage, to permit a limitedtravel of the carriage while said plate is locked to the rack bar. Therack bar 20 is swung inwardly by means of a multiple-space key 23 on alever 24 fulcrumed on the rod 3 and connected through a link 25 to anarm 26 fixed to the rock shaft 18, so that when the key 23 is depressedthe rack 20 will be swung inwardly to engage the tooth 21. The key 23also operates to lift the escapement rack 1 1 to permit the multipleletter-space movement of the carriage. The escapement rack is lifted bya roller 27 on a rock plate 28, over which extends an arm 29 fixed tothe rock shaft 18.

The slidable stop-plate 22 is mounted on a guide plate 30 fixed to thecarriage frame and having shouldered screws 31 extending through slots32 in the stop-plate 22, thereby permitting the stop plate to moverelatively to the carriage in a direction opposite to the forward travelof the carriage, or, in other words, when the stop-plate is held by therack 20, the carriage is permitted to jump forwardly a limited distance.The distance the carriage is permitted to move is determined by a stoppin 33 which may be set in any one of a series of openings 34 intheplate 22, said stop pin extending into a slot 35 in the plate 30, sothat when the stopplate 22 is connected, to the rack 20,'the travel ofthe carriage is limited by the end of the slot 35 being brought upagainst the stop pin 33.'

When the space key 23 is depressed and the rack 20 thereby swunginwardly to engage the tooth 21 on the stop-plate 22, the escapementrack 14 is also lifted to free he carriage so that the latter is movedforwarr ly by its spring 8 a distance determined by the position of theadjustable stop pin 33. l/Vhen the key 23 is released, it is returned byits spring 36, the rack 20 swings out and releases the stop-plate 22,and the escapement rack 14 reengages its pinion to lock the carriage.The plate 22, being released, is returned by a spring 37.

The teeth on the rack 20 are preferably at letter-space distances apartso'that the tooth 21 may engage the rack 20 while the carriage is at anynormal position of rest throughout its range of travel. The openings 34for the stop pin 33 are also preferably letter-space distances apart, asmeasured in the direction of the carriage travel, so that the stop pinmay be adjusted to effect a movement of the carriage equal to anydesired number of letter spaces within the limits of adjustment of thestop pin.

In order to provide for jump movements or multiple letter-spacemovements of the carriage through different distances, and mdependentlycontrolled by separate keys, additional mechanism is provided wlnch isin many respects similar to that already described. This additionalmechanism may per rack )1" act of rack teeth 38 cooperating with astop-plate l8, and a lower rack or set of rack teeth 38" forming part ofthe tabulating mechanism.

For eX- I The tooth e ured directly to the hmthe fin Z :5 sh wn in Fig. 1 set in hosinon to ruert the movement of thecarriage tha ing five letter spaces; the key 2 3 controlling said stopmight there fore beused for the usual spacing between sentences. Thelower stop pin 33 (as shownl being set to eilect the movement of thecarriage through ten letter-spaces, the key 16 might be used forindenting at the beirinning of paragraphs. dither key might also be usedin billing and other work for rapidly moving the carriage through aconsiderable distance by depressing the key a number of times insuccession. The multiple-space inenfhanism is also adapted for ui'iousother combinations and uses. The k y mavalso be used as a tabulator keyto cause the carriage to run forwardly to predetermined fixed positions;the rack bar 38 in this instance forming part of a. tabulator mechanism,and for this purpose being provided with a lower rack or set of rackteeth 38 for holding in adjusted p0- sition column stops 53 slidablymounted on a rod 5% parallel with the rock shaft 18. The stops 53 haveteeth to interlock with the rack teetlriS when the stops are swungforwardly to operative position, as shown in Fig. 3. Each stop 53 alsohas a forward extension 56 movable into the path of a counter-stop 57 onthe carriage, S0 that when a column stop 53 is locked to the rack 38,and the rack swung forwardly by operatin the key 46, the travel of thecarriage wil be limited by the counter-stop 57 striking the columnstop,as shown in Fig. 3.

When it is desired to use the key 46 as a tahulator key, the tooth 49 onthe sliding stop plate 48 is moved to inoperative position, and one ormore of the column stops 53 are adjusted along the rack bar and lockedthereto. Each of the column stops 53 may be provided with a pointer orindi; cator 58 which, when the stop is in operative position, lies overa scale 59 extending along the rack bar 38. to indicate the position ofthe stop. The operation of the key e6, will now release the carriage andpermit it to move forwardly until arrested by the first column stop inthe path of the counterstop on the carriage. 'hen the key -16 is thusused as a tabulator key, the key 23 may be used for spacing betweensentences, etc.

Although I have shown two swinging racks which may be separatelyoperated, the invention is not limited to two. The adjustahle stops onthe carriage may also be used in tabulator work, the multiple-space keysbeing operable to move the carriage from one column to another, and thestops being adjusted for different spacings so that the carriage willmove from one column to a position in the neXt column. corresponding tothe multiplws iiace key which erated.

is op Althou h I have shown two racks 38 and 38* arranged respectivelyto cooperate with the multiple-space stop plate and to adjustably holdthe column stops, my invention is not limited to the use of two racksfor this purpose.
